The invention relates to a method for applying to SO 2 The flue gas mixer for measuring concentration comprises a flue gas inlet pipe bundle, a shell, spoilers and a flue gas outlet pipe, wherein a plurality of strands of flue gas inlet pipe bundles are uniformly arranged on the left side of the shell at intervals and penetrate into a cavity of the mixer, the flue gas outlet pipe is arranged on the right side of the top surface of the shell, and the spoilers are fixedly arranged on the wall of the cavity in the cavity of the mixer. The invention heats the flue gas in the whole process, and solves the problem of SO 2 The problem of interference on detection due to the fact that the water-soluble particles are easily dissolved in water is solved, and accuracy of a measuring result is guaranteed. According to the invention, the plurality of spoilers are arranged in the mixer, so that the flue gas is fully and uniformly mixed, and the uniformity of the flue gas is ensured. |
